BCM84740 Status
The LASI signal from the BCM84740 is individually connected to the RTM FPGA to allow it to be
monitored by software. The LASI signal can also generate an interrupt to the front blade. Refer
to
Chapter 4, GPS Connectors, on page 48
for further details.
4.6.6
Fabric QSFP+ Connection
The QSFP+ cage accepts industry standard QSFP+ optical modules. It also accepts QSFP+
copper and optical direct-attach cables. The site is designed to support power level 2 modules
which are rated up to 2W (Refer to the ATCA-F140 Installation and Use Manual for a list of
QSFP+ devices tested with this product). The QSFP+ connector assignment for the 40Gbps
serial interface is described in
Table 4-9"QSFP+ Connector Pin Assignment"
.
